Timmy: Titanium has an atomic number of 22, which means it has 22 protons.  The average mass is closest to 48 which means the number of protons and neutrons should add to 48.  If there are 22 protons, then there are 26 neutrons.  The charge is 2+ which means there are two more electrons than protons, so there are 24 electrons.   Answer: protons=22, neutrons=26, electrons=24 ONE of Timmy's answers is incorrect.  Explain the mistake that Timmy made AND what the correct answer should be.
